PIPE-M OLDING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 261,960, dated August1, 1882.

' Application mediaan-,1123, 1882. (No model.)

To altuwhom it may concern:

Bc it known that I, FREDERICK SHIGKLE, of St. Louis, Missouri, have madea new and useful Improvement in Apparatus for Molding Pipes and otherLong Heavy Castings, of which the following is a full, clear, and exactdescription, reference being had to the annexed drawings, making part ofthis specification, in Which' Y Figure l is a view in perspective of theimprovement, the iiask being opened, and in two of the compartments thesand and pipes being shown; Fig. 2, a plan,'two ofthe compartments beingilled; Fig. 3, a horizontal section taken on the line 3 3 of Fig. 4.Fig. 4, a vertical section taken on the line 4 4 of Fig. 2; Fig. 5, asection similar to that of Fig. 3, but showing additional compartments;Fig. 6, another horizontal sectionrillustrating a modification in therelative arrangement of the compartments of the flask; Fig. 7, a vertical section taken on the line 7 7 ot Fig. 8; and Fig. 8, a horizontalsection taken ou the line 8 8 of Fig. 7.

the ask being hinged to the central onelat.

each side thereof, respectively, and forming the copes to the drags ot'the centralpart.

A, Figs. 1, 2, 3, 4, represent an approved form of the flask inquestion, having the central part, a, and the two side parts, a a', thepart a being furnished with suitable brackets-such as t2-for attachingthe iiask tothe pit-wall, and the parts a a being hinged Vat ai a3 tothe central part, c. As shown in the ligures named, the flask is made toform two pairs, B B and B B', of molding compartments, the central part,a., forming the drags b b b b, and the outer parts, a c', the copes b bbI b', of the various molds.

The pit-wall is not shown, as its construction is well understood, andheilig similar to that shown in patents previously granted nne` forinstance, No. 209,139. The iiasks are also, so far as the detailsthereof are concerned, mainlyr as shown in the patent named.

The -tlaskbottom O can be connected with the tlask-bod yin any desirablemanner, the bottom either being entirely removable from the remainder ofthe construction, hinged to the Hash-body so as to drop downwardtherefrom, made in sections or in a single piece, or it may be as shownin the drawings-that is, the bottom O is permanently connected withthecentral part, a, and when the parts a a' are opened away from thepart a, as shown in Fig. 1 and indicated by the broken lines in Fig. 3,the bottom projects laterally from the central part, as shown in Fig. 1.

The chill or bead ring D is made in sections d d, two or more, and theshell at of the ask does not preferably project or conne directly overthe chill-ring, enabling the pipe E, with the inner section of the ring,to be drawn directl y upward in the iiask.

It is evidentvthat a iask constructed upon the present plan can haveone, two, three, or more pairs of molding compartments. In Fig. 5a iiaskhaving three pairs, B B B B B2 B2, is shown. In such cases, or even when`oni y two pairs are used, it is desirable, in additionto the outsidefastenings, F F, to have tiebolts Gr G passed laterally through thetlask and fastened by suitable keys,ff.

The molding-compartments B B B B need not be in all cases exactlyopposite each other, but-may be arranged as shown, for instance, in Fig.6. Nor is it necessary `for the drags ot' the various pairs to comeclose together at their backs. On the other hand, the dra-gs on one sideof the part a must not come solidly and continuously against the dragson the oppositeside of the part a; but a space, P, or spaces must beleft, as shown, to provide for venting the gases from the sand ofthedrags,

for the present iiask involves the use of sand, and thegases therefromin casting could not pass ott unless a space or spaces in the interiorofthe part a were provided to receive the gases. The latter issuethrough` the many small perforationsp pp in the shell ot' the iiask,passing into the space described in the interior ofthe part a., andthence to the outer air.

IOO

l clailn l. The combination, in a flask where sand or clay is used formolding pipes and other` castings, of the central part, a, and the side5V parts, a a', said central part, a, having between the drags a spaceor spaces, for the pun pose described.

2. The combination, in a flask Where sand or clay is used, of the parta, the parts a a', and the bottom G a,having between the drags 1otherein a space 0r spaces for Venting the gases from the drags,substantially as described.
